In the 5th Pass H Separator LCW flow drops gradually ( allegedly due to a cavitation) and resonance control system compensate it by reducing LCW heater power ( blue line). From time to time ( 24 h or so) RF personnel needs to manually adjust flow to avoid the flow drops below the operability level. An additional issues of RF field modulation can be observed ( lines green,red,brown and black) while system becomes too warm. While the vector sum of cavity fields remains constant, individual cavities field undergoes a 2-3 % of modulation.

eosasw1 was fried when the UPS in rack 1H75L03 went into an inconsistent state. By this, I mean that the front panel was simply showing battery capacity 0 and it was unresponsive when using any of the front panel buttons. The switch was replaced and we deployed a small dedicated UPS for the new switch. We will deploy one of our standard UPSs for the switch when running completes.

1L25 again. Since there are only 29 C100 FSDs in figure 1, the six fault bits for cavities 3 and 4 are probably redundent.
